WATCH-CASE BOW.

's1 mtncAu5;0Ntoin-in mmeters Patent esasaduatd March 19, 18 89.

Application filed August 25, lacs.

' To all whom, it may concern/.- 'Be'it known that I, JQNATHAN H. COOPER, of "Marshall, in the county of Harrison and State of Texas, have invented certain new and 5 useful Improvements in Watch-Bow Fastenings; andl do hereby declare that the'following is a full, clear, and exact description of the "invention-,which will enable others skilled in the art towhicli it appertains to make and use 10 the same,reference being had to the accompa- 1 nying drawings andto the letters of reference which form part of this specificat1on'.;,= V

My inventionrelates to animprovement in "Heretofore watch-bows have been fastened to-the pendants in various manners. For instance, the ends'of the bow have been pro vided with heads fastened to the bow .bybe- 2:) ing secured in: holes in the sides of the same, the two ends of the bow extending through the heads on said ends will extend into the interior ofv thependant, and are held in this T by'a locking plate-consisting of a slotted tube or segment of a tube slipped into the inside of the pendant with its slots embracing the contracted portions of the bow ends behind beyond the locking-plate.

It is also well known that rotating stems have been fastened in watch-pendants to allow'rotatory movement and prevent longitudinal play of the stem by one or more pins or screws extending through the pendant into an annular groove in the stem.

The object of my invention is to provide a strong, exce'edingly'cheap, simple, and dura- 4o ble manner of securing the bow to the pendant of a watch, and one that will avoid and overcome all the numerous disadvantages of the old devices heretofore in use, and whereby the bow is firmly yet loosely secured to the same without removingthe stem of the watch or interfering with the interior'of the pendant, and also one that can be used with any kind of a watch, whether the case is a key or stem lever or pendant set.

\Vith these ends in view my invention con- Figure l isan elevation of a watch-casef 1 Serial m zssnov. (No model.)

I sistsin the combination of a watch-pendant,

a pair of radially-projecting bosses or annular flanges secured to or formed with the pendant and located diametrically opposite onthe' pe- 5 5 ripher-y of the same, a watch-bow'the ends of which are provided with annular grooves and, t loosely fit in saidb'osses, so that the grooves'T' will also be located in the same, said bosses being provided with radial'threaded openings,

and set-screws extending from the periphery of, the bosses through said openingsjremova; bly into the annular grooves'ot the bow ends,,- rwhereby the bowv is -firmly yet loosely secured totthe pendant. 5 j;

bow,'and pendant. Fig. 2 is a detail view of the bow, dotted lines representingthe pendant.- Fig. 3 is a view of a. bow and pendant th section. Fig. 4 is a cross-section of the pendant on line .2 :10, Fig. 3, the bow being turned to one sideand shown in section. 'Fig. 5 is a detail longitudinal section of the pendant, showing the annular bosses or flanges formed '7 5 on the same. I g In thedrawings, the reference-letter a indicates any suitable watch-case, preferably inclosing a stem-winding or keyless watch and provided with a pendant, b. 8o Apair of annular flanges or bosses,c c, are

. formed upon diametrically-opposite points on the periphery of the pendant and extending radially from the same in opposite directions, and said bosses are formed of a suitable diameter and length and of strong material. After the bosses have been formed apertures are drilled or otherwise formed through the pendant, so that the bosses will surround the same, and the apertures thus will be diamet- 9o rically opposite.

d indicates a watch-bow of any suitable construction provided at its opposite ends with annular grooves e e,located a suitable distance from the extreme ends, as shown. A screw-threaded hole is tapped or other-' wise formed radially through the side of one boss or flange, c, to receive a setscrew, f, adapted to project into the interior of the boss. A similar screw threaded hole is formed through boss 0, although preferably upon the side diametrically opposite the side of the 'through the same into the pendant, and the set-screw in that boss is then screwed so as to project into the annular groove in the end of the how. The opposite end of the bow is then sprung into the opposite boss and the screw 'in that boss screwed into the annular groove.

-: The bow is thus secured to the pendant and yet'allowed to swing upon the same as a pivot, and can be removed by unscrewing the set-screws.

It-is clearly evident thatiny fastening differs from theold fastening, before described, x; in'nran'y essential particulars, in view of the fact that'said old fastening can only be used on hunting case' io'rjopen-face lever-set watches,

: andcannot befused forpendan'tPset cases, be:

.Be of the locking-plate,'and as the ends of th bow necessarily project beyond the inner f ofxsaidplate and on account of. the neto screw, in the setting device. This rt-im'po t ntsas. la eln r o now used are'pefndant set; and, fthis oldfastening is used the not'befdetached without removing and getting into the'interiorof the further, Wi r fcuttingscrew threads, inside the pendant; hence they do not and could not use flanges or bosses, which are essential in my device, and it is by reason of these flanges that the bow is secured to the exterior of the pendant, and can be removed or replaced, or placed upon any watch, without interfering in any way with the interior of the pendant.

\Vhat I claim is- The combination of a watch-pendant, a pairof radially projecting annular bosses or flanges secured to or formed with the pendant and located 1 diametrically opposite on the periphery of the same, a watch-bow having its ends provided with annular grooves and loosely fitting in said bosses, so that the grooves will also be located in the same, said bosses being provided with radial threaded openings, and setrscrews extending from the periphery of the bosses through said openings removably into the annular grooves of the bow ends, for the purpose and in the manner substantially as described.

, In testimony that I claim the foregoing as J. F. DAvrs,
